TRIMPAC® MODEL D-1 & D-1B SUREFIRE® SINGLE INTERLOCKED PREACTION

The Viking SUREFIRE® SIngle Interlock Preaction TRIMPAC® Model D-1 and D-1B used with either a Model F Deluge Valve, a Viking Easy Riser check valve, a VFR-500 Release Control Panel and all associated trim piping form a unique operating system. The system piping is normally dry and pnuematically pressurized to supervise the integrity of the piping, fitting and sprinklers and provide the failsafe operation of the system upon loss of the primary and secondary power supplies. Preaction systems are commonly used to help minimize accidential water damage and still provide fast water discharge during a fire emergency.

The Viking SUREFIRE® Single Interlock Preaction TRIMPAC® Model D-1 & D-1B is a factory-assembled and factory-tested unit. The enclosure incorporates access doors for the emergency release, alarm test valve, view ports for the prime, and water supply pressure gauges. The TRIMPAC® Model D-1 and D-1B eliminates the field assembly of the deluge valve trim and release module piping. The enclosure protects the trim from damage or inadvertent operation. The included stainless steel hoses (or field provided piping) from the deluge valve to the enclosure assembly allows the TRIMPAC® Model D-1 & D-1B to be installed remotely from the sprinkler system riser. A valve drain package is required for the deluge valve and is ordered based on the size of the deluge valve. See Figures 12 and 13 for drain trim charts.

Note: Viking SUREFIRE® Single Interlock Preaction TRIMPAC® D-1 & D-1B is a complete system, and is listed as a unit. As such, it is normally not possible to modify the components of the system or their inter-relationship without comprising the listing.
